Theta Coolant 25 | Synthetic Centrifugal PAG/POE Compressor Oil - 55 Gallons

Theta Coolant 25 | Synthetic Centrifugal Compressor Oil ISO 25 - 55 Gallons

Theta Coolant 25 is a synthetic ISO 25 centrifugal air compressor oil engineered specifically for centrifugal compressor applications requiring exceptional thermal stability, oxidation resistance, and extended equipment protection. Supplied in a 55-gallon drum, this high-performance formulation is designed for industrial facilities operating large-frame centrifugal compressors under continuous-duty conditions.

Formulated from a blend of polyalkylene glycol (PAG) base chemistry and advanced performance additives, Theta Coolant 25 delivers excellent resistance to varnish formation and oxidation-related degradation. Its stable ISO 25 viscosity (25 cSt @ 40°C) supports reliable lubrication across high-speed centrifugal compressor bearings and gear assemblies.

With an extended service life of up to 24,000 hours at temperatures up to 200°F, this centrifugal compressor lubricant is built for long drain intervals, reduced maintenance frequency, and dependable performance in demanding industrial environments. The 55-gallon drum format is ideal for centralized lubrication systems and high-volume plant operations.
